Portable air-con units are great to take from room to room as needed throughout the day, but they may also be put in in your window for those who select. Most of them want to take a seat a bit away from the wall so they do take up a bit extra flooring house than you may count on. Most air conditioners provide a host of modes to choose from with completely different fan and cooling speeds, as well as having the ability to dehumidify the air.

Choose An HVAC Profession?

HVAC control components are used for numerous capabilities in family, industrial and transport sector. They usually do so in vehicles which are stocked with the alternative parts and supplies needed to complete routine assignments. An area service technician often handles every step within the course of besides the first, which is normally carried out by a dispatcher.

In a central service facility, the service technician is often accountable just for step 4 within the course of, with the remaining capabilities carried out by counter gross sales and administrative personnel. The obvious requirement common to all service technicians is thorough, specialized coaching and expertise in a particular discipline of experience.

In addition, some technical fields require an apprenticeship, certification, or licensing; others might only require on-the-job coaching by an employer. Few things symbolize a service firm more poorly than an unkempt technician driving a shabby, disorganized service truck. For a person with mechanical aptitude who enjoys working together with his or her hands, there are a number of advantages to a profession as a service technician. Training is offered on the technician stage as well as pre-apprenticeship and full apprenticeship ranges.

The mandatory entry-degree coaching is usually obtainable at a fraction of the cost of a bachelor’s degree, and should require much less time as effectively. Depending on the business, and on the coaching and expertise of the individual, the compensation of service technicians could be very attractive, with pay rates effectively in extra of $15.00 per hour not uncommon in lots of areas. Improve training in refrigeration systems is offered on a component-time study foundation for those working within the business.

For these reasons, employment as a service technician is worthy of consideration by experienced personnel seeking a career change, as well as by persons coming into the workforce for the primary time. Sadly many of those effectively paying jobs aren’t filled as a result of companies can’t find folks with the necessary skills and need to do in-home training.

A Buyer’s Guide Energy Efficiency

With all the talk about saving energy, saving the environment, lowering your “carbon footprint” and being more eco-friendly, the average Joe can get a little confounded.

The efficiency of an appliance or energy system indicates the amount of energy used to perform a certain amount of work. The higher its energy consumption per unit of output, the less efficient the system.Like many other appliances, the lifetime cost of your indoor comfort system comprises its initial price and the ongoing costs of operation and maintenance. This means the cooling and heating systems you select today will continue to impact your finances for many years to come.For these reasons, investing in a high-efficiency comfort system makes sense.

Here are some standard ratings you may find when making a purchase:

AFUE – (Annual Fuel Utilization Efficiency)
A standard measurement of gas or oil burning efficiency. It’s how the efficiency of furnaces and boilers are rated. A higher AFUE percentage means a more efficient product.
COP – (Coefficient of Performance)
The measurement of how efficiently a heating or cooling system will operate at a single outdoor temperature condition. When applied to the heating modes of heat pumps, that temperature condition is usually 47°F. The higher the COP, the more efficient the system.
EER – (energy efficiency ratio)
A measure of how efficiently a cooling system will operate when the outdoor temperature is at a specific level (usually 95° F). The term EER is most commonly used when referring to window and unitary air conditioners and heat pumps, as well as water-source and geothermal heat pumps. A higher EER means the system is more efficient.
A program launched by the Environmental Protection Agency. Products bearing the Energy Star logo have met EPA’s stringent requirements for efficient use of our natural resources.
HSPF – (Heating Seasonal Performance Factor)
A standard measurement of electrical power as applied to heating with a heat pump. A higher HSPF rating means a more efficient product.
The measurement of how effectively a material resists the transfer of heat via conduction or, in other words, how well insulating is a material? The higher the R-value, the less heat transfer can take place.
SEER – (Standard Energy efficiency Ratio)
A standard measurement of electrical efficiency as applied to cooling with an air conditioner or heat pump. A higher SEER rating means a more efficient product.
The measurement of how much heat can be conducted through a building component (such as a wall or window). How poor of an insulator is an object? The higher the U-value, the more heat the material(s) will allow to be transferred through it.

Other Energy efficiency Factors

Although the efficiency of your cooling and heating equipment will have the greatest impact on your energy usage, other factors can help reduce energy costs such as:

Maintain Proper Humidity
When cooling during the warm humid months, you will feel more comfortable at a higher temperature if the humidity level in your home is kept at 40-60%. This will reduce the load on your equipment and can save up to 20% in cooling costs.

Condition Only Occupied Rooms
Zoning or programmable thermostats can control your equipment according to your family’s lifestyle and daily occupancy schedule. This allows you to eliminate the wasted energy of air conditioned areas in your home that are unused or unoccupied.

Keep Equipment Clean
Regularly scheduled professional maintenance is also crucial to maintaining your system’s maximum efficiency. Your system should be checked twice a year prior to the summer and winter months. 

Spring Means Pollen And That Can Spell Trouble For Many People


Uless you upgrade with “Indoor Air Quality” add-ons for your air conditioning and heating system.  With the amount of spring pollen floating in the air four times greater than what people consider it to be high, spring allergy sufferers may wonder what in the world hit them. The change of season starts with you experiencing watery eyes and sneezing.  Allergy sufferers, familiar with the perils of high pollen, have learned to stay indoors.  From eye allergies (conjunctivitis) to skin reactions (dermatitis), spring pollen spells trouble for many people by making a large impact on quality of life.   Fortunately, you can control spring pollen triggers and make your home a dramatically healthier place for you and your family by filtering the air, controlling humidity, and cycling fresh outdoor air into the home.  These add-ons can help reduce allergies, prevent asthma, and even boost productivity.

Indoor air quality can be maintained by your HVAC in four ways.


Consumer demand for air cleaners has been on the rise in recent years according to the US Environmental Protection Agency (EPA).  Air filtration efficiency depends on the type of air cleaner used, and the type, number and size of the particles in the air stream. . You can bring fresh air into your home with the efficient and hard-working Bryant Evolution and Preferred Purifiers, Cleaners and Filters that keep your air warm and fresh during longer heating seasons — forcing fusty air and pollutants out of your home.  That means better air for your family to breathe.


If you have a home built in the last 10 years, the building regulations may have required your home to be tightly built for energy efficiency.  But that same tightness can also restrict the intake of fresh air and trap potentially hazardous indoor air pollutants, such as humidity, dry air, wood material off-gassing, cleaning agents, radon, carbon monoxide/dioxide and odors from people themselves.  One way to improve indoor air flow and protect your heating power is to install a ventilator that helps your family breaths easier during spring season by adding fresh, pre-filtered outdoor air to your home.  Furnace energy efficiency remains unchanged, pollutants and humidity better controlled.


Lack of humidity control can keep a home damp and sticky, while excessive dryness can crack woodwork and antiques, or create static electricity or dry skin.  Humidifiers operate by the principle that vapor is created when warm dry air is blown over a water-soaked area or through evaporated steam from heat water.  As the vapor or steam circulates, the relative humidity rises in the living area.   You can control moisture to improve air quality at home.  A humidifier directs just the right amount of moisture vapor into furnace ducts for greater whole-house comfort and less static electricity with its quiet, energy-efficient operation and two capacity models make it right at home, anywhere.


Duct systems are used to distribute conditioned air throughout houses with forced-air heating and cooling systems.   A typical house will lose nearly 20 – 40 percent of the air moving through its duct system due to leaks, punctures, and poor duct connections with the results being higher utility bills.   Is it difficult keeping the house comfortable, seemingly forever resetting the thermostat?  A duct system that is well-designed, properly sealed and cleaned can make your home more comfortable, energy efficient, and safer.   Consult your dealer, who will assess your air-quality controls and provide you with the best options for you and the comfort of your family.

Your HVAC System Needs Spring Cleaning Too

There is a lot of  debate as to whether getting a heating, ventilation and air conditioning duct system (HVAC) cleaned to coincide with daylight savings time or “spring forward” is necessary in every home.   According to the U.S. Environmental Protection Agency (EPA), routine cleaning of the air ducts is not necessary unless you have a fuel burning furnace, fireplace or stove that heats up the home through the ducts; and they should be cleaned on a case by case basis.   For the other components of the HVAC system, there are multiple advantages to having them cleaned regularly so it makes good sense to remember to spring clean your HVAC systems too.

Let’s see . . .  what are the advantages for cleaning your HVAC components this spring?

HVAC systems are used in the home and have ducts throughout the house where cool and warm air flow to keep your home at a comfortable temperature.  You can set the system to fan, which keeps the air in your home circulating without cooling or heating it.


Having your HVAC ducts cleaned can get rid of a mold problem. If you peek inside your air ducts or you smell a musty smell, you may have mold.   The EPA states that some substances may just look like mold, before going to the expense of having the ducts cleaned, you may want to schedule your technician to have a sample tested for positive confirmation of mold.  If you do in fact have mold, you need have your ducts cleaned because mold can cause serious health problems, especially in your respiratory system.  You also need to diagnose what caused the mold and have that fixed, as well as replace the insulation, if any, inside your air ducts.


Having your HVAC ducts cleaned can get rid of the nasty and dangerous remnants of vermin.  If you have an infestation of rodents or insects in your ducts, you really passing through your air.  In addition, pests carry bacteria, viruses, parasites and fungi that can cause illnesses.  It is better to have your technician come in and service your HVAC system.  If pests are detected, you will need to schedule a pest control service too.

Dirty Ducts

Having your HVAC ducts cleaned can clear the ducts of dirt, dust and debris overtime.  This build up can affect the system’s ability to function at full power.  Talk to a trusted technician, who will determine if it is really enough dirt, dust and debris to warrant a cleaning.


Having your HVAC ducts cleaned can help your allergies.  As mentioned above, you may have build up of dirt, dust and debris, or even pollen.  If you notice your allergies getting worse, it may be an indication that your ducts are dirty.  You may only need to replace your filters, or it may be something else entirely.  Talk to your dealer today.  They are eager to help folks keep their families comfortable and healthy, you realize the importance of having advanced technology on your side for your spring HVAC cleaning needs.

Ways to Save Money and the Environment

  1. Turn off the lights. When you leave a room or if you can open the blinds save the lights and save energy.
  2. Use cold water. Not to bathe, but to wash your clothes. Using full loads with cold water will cut down energy consumption dramatically. Much of the energy used to wash clothes comes from heating the water. There are special “cold water” detergents available at your grocery store.
  3. Close off unused room doors along with their ducts. That guest room or in home office can be closed to cut down on total square feet to be cooled or heated. Open the room 15-30 minutes before you plan to use it.
  4. Keep the sun out! Close blinds and drapes, install awnings if it’s reasonable. Don’t lose use of your windows, but cut down on direct sunlight during peak hours to see the benefit.
  5. Seal leaks. Windows and doors are obvious culprits but how much attention are you paying to your duct work? It accounts for the majority of house leaks. Professional HVAC technicians can help find these leaks. Make sure to find a certified contractor and ask about specials. Some dealers carry discounts or offer free inspections. Doesn’t hurt to ask.
  6. Invest in weather-stripping kits if you’ve got drafty doors.
    Install energy efficient ceiling fans. Or use an energy efficient portable fan.
  7. Fans are best at cooling you, not the room temperature. So take care to turn fans off when you’re not around.
  8. Paint your house a light color. Just like with clothes, cars and asphalt dark attracts and absorbs heat.
  9. Landscape. Reduce cooling costs by 30% with nature. Be extra eco-friendly and stick to indigenous trees and shrubs for desired shade. Don’t OVER
  10. Landscape. Ensure adequate space around your AC unit for dispensing heated air from your house.
  11. Tint your windows. This helps reduce heat absorption without blocking natural light.
  12. Grill-out. Your oven and stove aren’t just making you hot! They’re heating the house making your AC work overtime. However, in winter ovens can give your heating unit a hand.
  13. Remove air vent obstructions. Shelves, boxes, beds, etc should be moved from blocking vents.
  14. Windows don’t allow circulation when closed, neither do air vents.
  15. Ventillation moves the air which is good for your home year round.
  16. Get a home energy audit every couple of years. Believe it or not your power company can help you cut costs.
  17. Participate in your power company’s special energy-saving programs.
  18. Some programs shut down electric appliances for short bursts of time during peak hours. You hardly notice the difference, except in your energy bill.
  19. Check with your utility company about rebates. Some companies offer rebates when energy-saving equipment is installed.
  20. Turn down your home thermostat two (2) degrees. Save 24 kilowatt hours per month. It might not sound like a lot, but it adds up and you’ll hardly notice a difference in comfort level.
  21. Buy a programmable thermostat, especially if you aren’t home most of the day. Set it to turn on a half hour before anyone normally arrives home.
  22. Adjust your thermostat to a comfortable temperature and wait. Making major adjustments wastes energy and increases costs. Maybe it’s your body temperature that’s not not the house. Let your body temperature adjust before reaching for the thermostat.
  23. Lower your water heater thermostat by 10 degrees, but no lower than 120 degrees. This gives you all the hot water you need and saves 25 kilowatts per month.
  24. Fix leaky faucets – one drip per second equals 20 kilowatts per month.
  25. Change your bulbs. Compact fluorescent (CF) bulbs are more energy-efficient, last for years instead of months, consume very little power and generate little heat. Incandescent bulbs are a waste. (Warning: CF bulbs shouldnever be placed on a dimmer)
  26. Turn off your computer when not in use or, at the very least change it to energy-saving “sleep” mode.
  27. Buy Energy Star rated appliances when replacing your old appliances.
  28. Energy Star shows the appliance meets or exceeds the U.S. Department of
  29. Energy and the Environmental Protection Agency standards.
  30. Consider a front loading washing machine. Use 50% less energy and one-third the water by front loading. Plus, these styles remove more water during the spin cycle which translates into energy savings for your dryer.



In this sluggish economy, which has many homeowners hesitant to move forward with big home improvement projects, the home performance trend is an opportunity for consumers to upgrade their heating, ventilation and air conditioner (HVAC) systems and take advantage of federal incentives.  There are also very healthy rebates in some states, where you can easily go from a cool comfortable family room to a broiling, sticky room during peak hours on hot summer days.  More current cooling models are up to 30 percent more energy efficient than those of a decade ago and carry warranties as long as five years. Best of all, buying an air conditioner early — before summer, when retailers get top dollar — can save you money.   Make your next shopping consideration based on these key trends.


Building more energy efficient homes means installing units that exceed government standards for energy efficiency referred as Energy Efficiency Ratio (EER), which is the cooling capacity divided by the electrical power required to run the unit. The higher this number is, the better.  Building energy efficient homes also means installing thermostats and ductwork for maximum efficiency.  A home with hot and cold spots most likely means the HVAC system is laboring to maintain the correct household temperature.  Going from a EER of 9 to a EER of 13 could add up to $100 to the price tag. But you can easily amortize that cost over the life of the unit in energy savings. Check the Energy Guide label on any unit you’re considering to find its estimated operating cost.


Another trend in the world of HVAC is utilizing methods to improve indoor air quality.  Choosing the right control features will also make it easier to keep cool this summer.  Homeowners are becoming increasingly aware of the negative health effects of poor indoor air quality, and consequentially are asking for their home heating and cooling systems to include advanced air filtration systems. The new air filtration systems help keep indoor air free from allergens and dust; and in some cases, they can even rid the air of certain types of bacteria and airborne viruses.  It’s interesting to note that for a while homes were built so air tight the house could not “breathe.”  This caused condensation build-up and eventual damage to window frames and sheetrock.  Worse, the air quality declined making the air the family was breathing unhealthy.  HVAC companies like Carrier are continually working to improve the air exchange process so the household air is always kept fresh and free of mold and bacteria.  Because innovation is a way of life for CarrierMA, their expert air conditioning and heating engineers focus on using intelligent design and technology to develop efficient, precisely engineered heating and cooling systems.


When you look into the future of HVAC, it’s an amazing world of high tech service.  10 years from now, many home units may likely have wireless communication with service facilities monitoring the operation of your unit.  When your unit is not operating properly and your air quality or energy usage does not meet the unit standards, you’ll be notified by an authorized service provider.

In short, today’s HVAC systems provide more effective heating and cooling, and the environmental benefits make these new systems as appealing to the eco-conscious homeowner as they are to the budget-minded one.   However, until the future arrives though, Mid-Atlantic Carrier Dealers are your reliable partners to make sure your home is as safe and energy efficient as possible given the current technology.

What is Humidity?

What is humidity? You have actually heard about it from the weather reports and quite often of course, but you have never known what it is. You are not alone because many people also do not know. There is more to humidity than people know, even those who think that they know about it all. For example, do you know what is humidity, relative humidity, absolute humidity and so forth? Chances are you only pay mind to the weather report when there is the mention of the word rain. Humidity is the amount of water vapor in the atmosphere. There are several ways of measuring humidity in the atmosphere but perhaps the most common one is relative humidity.

The humidity determines whether it will rain on a given day or not.  As you will find out when you read some more about humidity, if the humidity is 100%, then may rain. The humidity must be 100% near the area where the clouds are being formed and if so, chances of rain will be very high. You may wonder what is the point of all this but the truth is that humidity is very important to people. For example, if the humidity is high and the weather is hot, then that means that it could be a very uncomfortable day for you because your skin does not “breathe” and it feels clammy and sticky all over. As you seek the answer to the question: what is humidity? You need to know that for you to be comfortable even when you are indoors, then you must keep the level of humidity at optimum.

Too much or too little humidity may not be good for your health. In that case, you need to make sure that you know how to tell when the humidity is not good. For example, if you notice moisture on the windows, then there is probably too much moisture in the air. If you notice mold on the walls, on the clothes and on the furniture, it is because there is too much moisture in the air. If you life in high altitude areas, then most likely there are times of the year when you will experience too much humidity. It is for such times that you need to know what is humidity and what are the best dehumidifiers in the market to invest in.

To be sure about the level of humidity in the air, you need to invest in a hygrometer. This is just an instrument that is used to measure the level of moisture in the air. This instrument is sold in two types and will show the relative humidity in every room. You should know that relative humidity will not be the same in all rooms but it should be close. The electronic and the mechanical hygrometers come with their own distinct advantages. They both work in just about the same way but perhaps you want to know more about them before you buy. The best RH for the indoors is between 30%-50%. The good news is that once you know what is humidity, you can control it, that is, either lower or raise it.

Key Dehumidifier Features

Compiled below is a list of some things to look for when shopping for a dehumidifier. Many of these features come standard with pretty much all dehumidifier models, however some are designed for special applications and are only applicable for certain models.

Pint Capacity:
Pint capacity is the amount of moisture in pints that a dehumidifier model can remove from the surrounding area in 24 hours. Pint capacity is affected by the size of the area and the initial moisture within that area. Generally speaking, models with a pint capacity less than 70 pints are suitable for home or residential use as opposed to models with capacities greater than 70 pints which would be suitable for commercial applications.

Most residential home dehumidifier models are rated a pint capacity based on maximum relative humidity versus commercial models which are rated at typically 60% relative humidity.

Collection Tank or Collection Bucket:
Most home or residential dehumidifier models have an internal collection tank or bucket that can be removed when needed. Once a dehumidifier model extracts enough moisture to fill the collection tank, the tank most be emptied. Most models have an auto-shut off feature that turns the dehumidifier off once the tank is full.

Commercial or industrial dehumidifier models remove so much moisture from the air that a collection tank would be impractical. Thus, these models usually drain or pump the collected water as opposed to storing it in a tank.

Humidistat or Hydrostat:
A humidistat is an instrument that measures relative humidity within the environment and then relays that information back to the dehumidifier for any needed adjustments. Humidistats are built into dehumidifiers or can be bought separately.

Low Temperature Operation:
This is a feature found on dehumidifier models suited for use in low temperature environments such as basements or crawl spaces. Most models have an operating temperature range that should be more than suitable for most basements or crawl spaces, but there are some models that can operate in an environment as cold as 30°F.

Electronic or Manual Controls:
Most models on the market today feature electronic controls. The difference between the two is that electronic controls usually consist of settings controlled through a “button” type interface where as manual controls consist of settings controlled through a “dial.” One thing to note is that if power is interrupted, an electronic controlled model will turn off and will need to be manually turned back on.

Auto-restart is a function that can be very useful during power failures or power interruptions. If a dehumidifier model loses power, auto-restart functionality automatically turns the model back on at its previous settings once power is restored.

Caster Wheels:
Found on almost all dehumidifier models, caster wheels allow for easy transport and portability. Residential and commercial models alike can be found with caster wheels.

Air Filter:
Air filters are an optional accessory that function to help clean air being drawn into the dehumidifier. The basic process is that air is passed through the dehumidifier and through the filter, moisture is drawn from the air and collected in the collection tank and clean air is exhausted back out through the unit.

Noise Level:
While not necessarily a feature, a quiet dehumidifier is definitely better than a noisy one. Dehumidifiers are generally noisier than other appliances, and while many would not consider a decibel rating of 50 decibels to be quiet, it would be considered quiet for a dehumidifier.

Frequently Asked Questions About Dehumidifiers


What size of dehumidifier do I need?

The capacity that you need depends on several factors, the most important of which are the area that needs to be dehumidified and the humidity level in that area. Please view the following chart to approximate the capacity of the dehumidifier that you need

What does the capacity of the dehumidifier stand for?

Dehumidifiers are rated by the maximum amount of humidity that they will remove from the air in a 24 hour period. For example, a 40 pint dehumidifier is rated to remove 40 pints of moisture from the air in a 24 hour period. Keep in mind that even though the dehumidifier may be removing 40 pints of moisture a day the unit may only have a 25 pint storage tank so you will need to manually empty the reservoir bucket in order to achieve the unit’s maximum capacity. To avoid this issue you would need to purchase a unit that offers a direct drain option so the unit may continuously expel the moisture into a nearby drain in your area negating the need to manually empty the holding tank.

Which model would you suggest to help minimize my monthly utility costs?

Start by selecting a unit that is “Energy Star” rated. The Energy Star rating is an international designation indicating that an appliance has been deemed energy efficient. The dehumidifiers that offer this designation are clearly marked on our website. You will also need to make certain that you do not select a dehumidifier that is too small for the area you wish to cover and the humidity level that you wish to maintain. An undersized dehumidifier will run more often which will in turn use more energy than a properly sized unit.

Is it true that a dehumidifier may add some heat into the area in which it is located?

Yes, a dehumidifier will add some heat into its immediate environment. The amount of heat will vary greatly depending on the size of the unit and the area it is operating within. The warmer the temperature the unit is operating within the more efficiently the unit will be able to remove moisture from the air. It is conceivable in smaller areas that a dehumidifier may raise the ambient temperature 5 to 8 degrees. Conversely, a dehumidifier will cease to operate if the environment becomes too cold. This is an important factor to consider if you are attempting to dehumidify a basement area that is not heated. Check the specifications of the unit you are considering for more information on the units operating parameters.

I have a fair amount of square footage to dehumidify. Would I be better off with a “whole house” unit or a couple of smaller models?

While there are many models that claim to dehumidify large areas their true effectiveness is dictated by the airflow within the operating environment. If air is unable to easily flow from one room to another it will greatly reduce the effectiveness of a whole house unit. In these situations you may need to employ a ceiling fan or smaller portable fans to increase the airflow between the rooms and to the dehumidifier. Another option would be to purchase two smaller units and place them at opposite ends of the home.

Are dehumidifiers noisy?

Although noise is a very subjective topic, your average dehumidifier is usually not as loud as a window or portable air conditioning unit. A dehumidifier will make some noise during operation though so you may want to plan on locating the unit in another part of your home other than the bedroom.
